If you actually wanted to let the user see the highlighting of the wires to catch the interactions, then you really do want to generate diagrams. If what you want is the correct answer for a given set of Boolean inputs, then this is no problem. You were already going to have some way for the user to input the system they were describing. A table or series of tables could work, or if it is a simpler case, you could have a series of dialogs that fills in the table for them. Once you have the table, you can intrepret it. Look for 0 or 1 in the first cell. Then move to a higher column if TRUE and to a higher row if FALSE. If the logical progression is over, the cell will contain text instead of 0 or 1. Anyway, the details are up to you. You can definitely build a datastructure that encodes the truth table and interpret it with a fixed and simple diagram. Another approach to take? Let the user build the diagram using the case statements themself. You can build a simple palette set with nothing but what you want there. If RoboLab gives it to kids to build software for their LEGOs, you might be able to give it to your users. Greg McKaskle
